Yesterday, we reported on widespread accounts from users of Windows Phone 8 handsets, citing various issues with their brand new devices. Many owners of HTC's Windows Phone 8X have reported problems with the device randomly rebooting, often several times a day, with tweets like this one from earlier today becoming increasingly common:

Not recommending HTC8X to anyone right now. Phone has restarted five times. Three of them was today. Both during music playback.

Nokia's Lumia 920 has also suffered problems among owners, with some reporting seemingly random freezes, and many complaints about less-than-stellar battery life.

ZDNet's Mary Jo Foley is one of the many users who have experienced such issues; she reports that, although she's been using a HTC 8X since October 29, the handset got "stuck in an endless loop of continually trying to sync" her email accounts this morning, before it too spontaneously rebooted itself.

Mary Jo managed to get word back from Microsoft officials, who confirmed in an official statement: "We are currently investigating reports of these incidents." Of course, that's not exactly an immediate solution for those experiencing these issues, but it's a step in the right direction, and it's encouraging to see Microsoft acknowledging the problems on the record rather than trying to sweep them quietly aside.

That said, let's just take a moment to put this into context. It's not yet clear exactly how widespread this issue is, so do bear in mind that not everyone has been experiencing problems such as these - it doesn't affect all handsets by any means. Don't panic.

Well, not yet anyway.
